CONDENSATION PUMP AND RECEIVER.

Application filed May 31,

a condensation pump and receiver, particularly. adapted though notnecessarily limitedin its use in connection with a heating system, andone of the objects of the invention is to so'construct and arrange acondensation pump and receiver in which pump bearings, flexiblecouplings and supporting base for the various parts will be eliminated,thereby resulting in a considerable saving in the cost of manufactureand requiring a small floor space for installation.

In apparatus of this charactep it is desirable, and in fact quiteimportant, to establish a low water line. Heretofore it has beenfrequently necessary' .to install the apparatus below the floor leveland this is obviated to a large extent in the present invention bydispensing with the use of a supporting base and considerably loweringgravity intake to pump, the pump being of the vertical type allowing theimpeller to be located at a lower point thereby making it practical toestablish a low working level in 2 the receiver.

In the drawing- Figure 1 is a view partly in section, partly inelevation and partly broken away of a pump embodying the principles ofthis in- 3 vention and showing the same in connection with a receiver.

Figure 2 is a view in elevation of the pump unit to which any source ofsupply maly be connected.

eferring more particularly to the drawing the numeral 10 designates areceiver or container which is supported preferably by two short feet orprojections 11, which rest directly uponthe supporting surface or floor'12. These two feet are disposed near the center of gravity of thereceiver. A pump casing13 is provided with an inlet opening 14 and aflange 15 encompasssing the opening. The casing is supported by means ofa foot or projection 16 located near the center of gravity of the casingand rests upon the floor or supporting surface 12.

The flange 15 is connected directly'to a flange 10 on the wall of thereceiver 10 by means of suitable fastening devices 16 such as bolts orthe like. The flange 10 surrounds an outlet 17 of the container andwhich outlet 17 communicates with the in let 0 ning 14 in the pumpcasing 13.

' en the pump casing 13 is thus secured 1927. semi No. 195,403.

to the receiver 10 the entire structure will be supported by a threepoint support formed by the feet or projections 11 and 16, therebyobviating the necessity of supporting bases and eliminating strains onthe castings.

The pump casing 13 is provided with a discharge outlet 18 around which aflange 19 is arranged, and which latter flange is adapted to be securedto a pipe or the like for conveying away the liquid delivered from thepump casing through said outlet.

An impeller 20 is arranged within the casing 13 and is connected with ashaft 22 of a motor 23 preferably by a non-corrosive rigid coupling 21,preferably by telescoping the shaft into the coupling and then securingthem by means of a fastening device 24, such as'a screw, bolt or. thelike.

With this construction and being thereby able to locate the impeller ata low point in the casing so that the impeller will be rotatable about aVGItlCfil'flXlS, it is possible to establish a low working level for thepump.

The shaft or coupling 21- passes through a suitable stufling box 25.

The motor -23 is supported b the casing of the pump preferably upon aormation or supporting structure 26 to which the'motor casing isdirectly fastened preferably by means of bolts or the like 27, therebyrendering it ossible to readily remove the same when desired.

The supporting structure 26 is preferably connected with the top 28 ofthe pump casing, the latter being preferably removablysecured inpositionby fastening devices 29.

The support 26 may be of any desired construction either as an annularmember or as separate uprights, but when formed as an annular membersuitable openings 30 are provided therethrough to permit ready access tothe coupling device 24 and the stufling box 25.

The im eller will be suspended-by the motor sha t with the result thatpump bearings will be eliminated.

In Figure 1 the pump shown in connection with a receiver hile in Figure2 .the

pump is disclosed as a single and separate unitadapted to be connectedto any suitable source of supply. In the latter' form of the inventionany suitable number of supports or projections 16 may be employed tomaintain the pump elementin proper position for use.

With this im roved construction the parts to be accurate y machined arelight and easily handled and assembling simplified.

What is claimed as new is A condensation pump and receiver embodying asa unitary structure a receiver having a discharge outlet adjacent itsbottom with a flange engaging surface encomassing said outlet, a pumpcasing having an inletand a flange encompassing said inlet, meanssecuring said flange directly to said surface, said inlet communicatingwith said outlet, the casing of the pump being disposed in closeproximity to the supporting surface for the unit, said pump embodying animpeller rotatable about a vertical axis, and a motor supported directlyby the pump casing, said impeller-being located adjacent the bottom ofthe casing and suspended by the motor shaft, whereby a low working levelin the receiver will be obtained.-

In testimony whereof I have signed my name to this specification, onthis 27th day of May, A. ,D. 1927.
